But no matter how passionate you are about your product, you need a recipe for success. There's nothing simple about running a food business. You need a business plan and a distribution plan. You need to know state and federal food rules, licensing requirements and fees. Ignore these and you may well join the ranks of the many home-based businesses that fail.

In a series of interviews, AARP reached out to people who had created successful food businesses for insights into what an aspiring food entrepreneur should know before debuting the dream.

On average, 550 new woman-founded businesses opened up each day.
